WandaVision is currently releasing new episodes on Disney+, and the show has seen the Marvel Cinematic Universe take a whole new direction. Between the sitcom-style format and the exciting twists and turns, fans still do not know what to expect from the show's final five episodes. Since the series premiered, fans have learned some fun information from the show's head writer, Jac Schaeffer, who admitted she had "a lot of headaches" trying to figure out the complex story. During a recent interview with Desert News, Schaeffer was asked what the scariest part of creating the show was, and if there's anything that's been keeping her up at night during its run.
